In the OpenSUSE Tumbleweed offline install ISO files, I get multiple (i.e. hundreds) corrupted .rpm files for every recent snapshot, last tested with openSUSE-Tumbleweed-DVD-x86_64-Snapshot20220819-Media.iso. These corruptions have appeared in several snapshots since at least August 1st (oldest file I could get); they are reported by the installer and also 7Zip on Windows when run on the mounted image file. The SHA-256 checksums are correct in several cases that I have checked, meaning that the cause lies at or before ISO creation. All systems that I use for this have ECC RAM. Several (probably all) architectures/platforms are affected, not just x86_64.
The installer, that I run from DVD (I have burnt and tried many DVDs of several snapshots), reports multiple rpm files as corrupted (when I continue after the first error, that is). The affected files are different from snapshot to snapshot.
7Zip approves of every rpm file on the current Leap images, so I assume it can handle at least some rpm files. The errors I get are from 7Zip are often about.cpio files (edit: but the error would be from an encapsulating format, but does it need to decompress to check the CRC?):

What is the reason for using 7zip on an installation media at all? This is a useless/unnecessary/wrong usage at all. It seems that you alter the iso’s with 7zip and thats also the reason why you get so many complaints whilst installation later on…
Can you explain why you use 7zip for what reason and what are you doing?
No, you do not. You just need a program that writes image as image (effectively in dd mode) to the correct location on USB. There is dd for Windows, there is rawwrite with GUI and other programs that support raw image mode.
I ran into the errors when installing from DVD, then I investigated, and 7Zip appears to be useful. “7z.exe t” does not change the image.
It is the Tumbleweed INSTALLER that CANNOT READ the install files. And it HAS to work from DVD, or it is broken. I should have made screenshots, but I was not sure whether the DVD drive or some drivers damage the data.
To be clear you do not need 7zip for anything just do a direct binary copy (https://www.osforensics.com/tools/write-usb-images.html can be used) to the install media. for DVD do an ISO copy. The download ISO is ready without modification.
